This is the reason I never eat or drink near a laptop. Even if it does come back alive the damage is done. Liquids are working with the metals on circuit board to corrode connections. And even a small spill trips the liquid damage indicator dots that Apple puts all over the inside.
Too bad Apple is not like Lenovo thinkpads. They seal they key shafts and put the keyboard on a drain tray that routes liquids to drains in the bottom of the system. I have seen people dump a large coffee on them and continue working. Downside is they are a bit bulky.
THIS ^ Last year I spilled an entire mug of coffee into my P580 keyboard. It immediately got all kinds of graphic glitches before I could even shut it off. Turned it over, let everything drain and dry. Turned it back on and it worked...kind of. Still glitchy and many keys didn't work. Replaced the keyboard with an OEM ordered from Amazon ($12) and back in business, minus the track pad.
Bonus is I still get the french vanilla smell when it heats up!
